Minimum Sizes and Positions Too Small to Sell

Polymarket's exchange cannot sell a position smaller than 5 shares, at any price. A position under that floor is not lost. It waits for the market to resolve, and it still pays out normally if it wins. The only thing you give up is the option to exit early.

That floor is why Polycopy sizes bot copies the way it does. New bots target at least 8 shares per position, comfortably above the exchange minimum, so the positions they open stay sellable. It is also why every bot order has a $5 minimum. A smaller order could round down into a position too small to ever exit.

A flat ticket buys many shares when the price is low and few when it is high. At low prices the share floors never come into play at all. From around 62¢ upward, $5 no longer buys 8 shares, so from there on it is the floor rather than your ticket that sets the order size. Cheap contracts are untouched by any of this.

A quick copy from the feed is not bound by the bot's share target. It follows the market's own minimum, which is fetched per market and is well below the bot floor, and the copy panel shows the exact figure — "Minimum order is …" — before you confirm. The exchange's 5-share floor still applies underneath, so a manual copy on an expensive contract needs more dollars than one on a cheap contract to reach the same number of shares.

Nothing, and there is nothing you can do. A position under 5 shares cannot be sold in part or in whole, at any price, so it waits for the market to resolve and pays out normally if it wins. Buying more of the same outcome would lift the holding back above the floor, but that is adding risk to regain an exit, which is rarely worth it on a position this small. If a sell is being refused on a position that IS above the floor, that is a different problem — send us the market and the bot name at help@polycopy.app.
